I accidentally made two of them, but clicking on the "empty folders" icon created a new folder. Again, this aspect of the design will come back later.

Here is a look at the attributes selector of a file (in this case one of the new empty folders I just made). Note the presence of password protection. This is 1983; the Macintosh didn't have that en-masse until 1999, and consumer-grade Windows until 2001!

(Yes, I am aware that Windows 98 had support for user accounts. I do not consider that to be real filesystem-level security. Nor do I consider Windows NT to be consumer-grade Windows.)

The Lisa has dialog boxes, and does from time to time encounter errors, as you can see. It's probably complaining because I have in fact never used it, so those preferences never existed to start with.

Another interesting aspect of the system design is the idea of duplication. No, this isn't really a special idea when it comes down to normal files, or folders, or even programs. What is special is that it also applies to running program instances. In this case, I am attempting to duplicate the running clock application.

This is also how you are supposed to install programs; instead of dragging and dropping them, you are expected to make duplicates and then move the duplicates to the location you want to put them.

A look at the clipboard program, which is telling me I can't edit the clipboard...for some reason.
